Supported by the DOE's Advanced Scientific Computing Research (ASCR) program, the ALCF and its partner organization, the Oak Ridge Leadership Computing Facility, operate leadership-class supercomputers that are orders of magnitude more powerful than the systems typically used for open science.

ALCF computing resources—available to researchers from academia, industry, and government agencies—support large-scale, computationally intensive projects aimed at solving some of the world's most complex and challenging scientific problems. Through awards of supercomputing time and support services, the ALCF enables its users to accelerate the pace of discovery and innovation across disciplines.

The ALCF’s team of computational scientists, data scientists, performance engineers, system administrators, software developers, visualization experts, and support staff help ensure users get the most out of the facility’s high-performance computing systems. The ALCF also provides training and expertise to prepare researchers for the next generation of leadership computing resources.
